摘要: 個人通訊系統(PCS)在這幾年迅速崛起,整合各類無線通訊系統是 將來必然的趨勢。在這種整合的個人通訊環境下(multi-tierPCS),手機 可以使用高階(high-tier)或低階(low-tier)的個人通訊服務,這樣雖可 滿足多元化的通訊需求,但卻造成手機註冊行為更加頻繁。在本篇論文中 ,我們應用階層性分散式資料庫架構(hierarchically distributed database),讓整合型個人通訊環境中的網路資源得以節省,並減少行動 網路管理(mobility management)所需的資料庫存取,以避免資料庫成為 網路瓶頸。經過模擬分析所獲得的結果顯示,階層性架構可以大量的減少 手機註冊所需的網路訊息,並降低資料庫存取的次數。雖然此一架構需要 更改網路管理協定,且需要增加原有的資料庫容量,但它大量節省系統資 源的優點,提供了多階個人通訊環境下的另一個選擇。 Mobile communication has been experiencing a rapid growth in recent years. The integration of PCSs becomes the best important research. In multi-tier PCS environment, the network resource are more precious. In this thesis, we use the hierarchically distributed structure to reduce network message and database lookup in Multi-Tier PCS environment. Simulation results show the effectiveness of the proposed strategy. Although our strategy needs to modify the mobility management protocol and needs more database capacity, this architecture can provide the other choice for administrator to reduce the location update and call tracking cost significantly.
